Anyone know what the normal peak flow reading would be for someone who is 6ft, 24 years old. I am a smoker. I have read various websites and some say it should be 500 and others say not as much as that and one even said 630, I cant get near that ! I was just wondering. I dont suffer with asthma.
Any help would be great.
Thanks.

The chart with my meter says between 622-640. Yep, I would guess it's the smoking, too. For instance, my husband is 34, around 5' 9", and a smoker. His should be around 643 according to my chart, but he's doing good to get 350-400. I really wish he'd quit smoking, too, but so far nothing has induced him to do so. I'm hoping that maybe his bad levels are because he wasn't trying hard enough or didn't do it right, even though I explained how. For your health's sake, do quit smoking...I used to smoke, and I can tell you you'll feel so much better if you do quit.

Asthmatics have stronger respiratory muscles than normal people do,
probably because we make more efforts in our everyday breathing consciously or unconsciously.
Considering this, our peak flow should go (far) beyond the standard value for
normal people.

What is normal for a female, , 36 y.o. and 5'4"? I am guessing it is way above my top reading of 350. I work in a mold environment and this has caused me major breathing problems. It has been struggle with my employers to get this addressed, and I know that I cannot continue working in the environment for much longer. It has been very bad (the mold) for the past eight months. There is visible mold on many of the ceiling tiles.

I don't remember a chart coming with mine! I'm 59, 5'2", 107 lbs, run 8 miles a week, female and the best I can do is about 375-400. It doesn't keep me from doing anything...just take a couple of hits off the Albuterol, wait 15 min and go run, mow the grass, etc. I hoped after I got back to jogging that my peak flow might increase but it hasn't...oh well..

Titchou,
I would think running would strengthen your lungs and make your peak flow higher. I am 48, female, 5'2" and if I take my medications every day (Advair), my peak flow stays around 470-500. But if I try to jog/run, I can't go very far without getting out of breath. Of course, part of that I'm sure is being overweight! Right now I'm working on that at the gym; I power walk hoping to build up to a jog eventually.

I thought so too but it didn't seem to make much difference....since I never had a peak flow test when I didn't ahve asthma, I don't know what it would have been normally. Maybe I just have small lungs!

Its good at know what your normal is, esp if it is higher than the chart says. My reading is usually really good. I'm 21, 5'8" and I can get up to 550 on a good day. Before I got sick with Fibro I could get up to high 600's. I had an allergic reaction today and went to the health center. There the peak flow was low for me- highest was about 420. But because that is supposed to be normal, they said I was mostly ok. If they had looked at MY chart they would see it was not normal for me. And then they kept yelling at me to take slow deep breaths so I wouldn't hyperventilate. I wanted to yell back that maybe if they helped me (or at least got me a paper bag) I would do better, but of course I didn't have the breath or the energy to say any of this.

I used to play the flute in band and I know how to breath from physical therapy and aerobics and chi gong where I have had that really stressed so I'm always glad to have a good lung capacity. Of course, good can be relative.

It is relative - I agree, kyethra. My normal range is 490 to 550. (5'6", age 30) One day when I went to get allergy shots, I actually hit 560 once - but that was prior to the tree pollen coming out. Right now with the trees out, I am lucky to do 520. I really don't feel well if I am below 460 or so.
